Our Spindles do pretty much everything.

Dynomax has developed hundreds of modular spindles tailored to the market's requirements, including our new line of robot spindles.

Our spindles are designed to meet the required performance features:

• Desired Spindle Power- Peak and Continuous
• Maximum Spindle Load- Axial and Radial
• Maximum Spindle Speed Allowed
• Flexible Tooling Style, Size and Capacity for ATC
• Compatibility with multiple applications including:
• Milling Spindles
• Turning Spindles
• Grinding Spindles
• Boring Spindles
• Drilling Spindles

Developed as intelligent and innovative products, all Dynomax spindles are modular in design, allowing for quick customizations and upgrades.

What We Do….
When designing a new spindle, Dynomax engineers find the exact combination of machine components to meet customer requirements. Each component is carefully selected based on the benefits and limitations each offer, factors such as required speed, available space and maximum stiffness determine the final new spindle design.
The following is a brief overview of some of the considerations that effect precision spindle design.
Bearings
Bearings are important in spindle design as they dictate many performance factors. When designing new spindles Dynomax chooses the bearing(s) that optimize spindle performance. Some of the design considerations include…

• Required maximum speed
• Required stiffness
• Preferred lubrication method

Housing
When Dynomax designs custom spindles the housing typically relies on other spindle characteristics. Housings can be either totally or partially enclosed, determined based on elements such as bearings, shaft, motor and lubrication system.

Style
A spindle's style, either integral motor, belt-driven or gear-driven, plays a significant role in the driving characteristics achievable with a precision spindle. When determining which style will optimize performance, Dynomax considers the following

• Required spindle power
• Required speed
• Required torque
• Available space

Shaft
The shaft, the component that transfers power to the cutting tool as well as locates the bearings and tooling system, is another important design element. When designing a new spindle shaft, engineers must consider the following…

• Allowable bend
• Required loading factors
• Specified tooling

Motor
Essential to any spindle, is the motor. When designing a new spindle, the spindle motor may either be external or internal, depending on the spindles style. Each with their own benefits and limitations, spindle designers must consider the following when choosing the ideal motor.

• Required power
• Required speed
• Required torque
• Available space
• Possible interaction with chiller & VFD

Other Components
In addition to the basic design features, Dynomax engineers work with a variety of subcomponents that are used to improve a spindle’s life, performance and reliability. Experienced in designing spindles, engineers are able to enhance designs with seals, ceramic bearings, air purge options, drawbar upgrades, drives and more.
